| Under the trend of economic globalization,in the face of increasingly serious climate warming,reducing CO2 emissions and developing green economy have become the consensus of all countries in the world.Since the 13 th five-year plan,China's economic development at the expense of ecological environment has been condemned by the people.Therefore,it is urgent to adjust the economic development mode.China officially launched a national carbon trading market in December 2017 after five years of pilot work.Government attaches great importance to the work to reduce emissions and the awakening of awareness of low carbon are,dual pressure from all walks of life to take measures to reduce emissions,including in recent years,with the development of economy and the continuous development of auto industry,auto industry convenient people's life,but also greatly increased CO2 emissions,carbon emissions and the automobile industry can yet be regarded as an effective way to reduce CO2 emissions.But if only from the perspective of a single enterprise,the enterprise for carbon emissions monitoring,control,the control line companies cannot oversight,and many enterprises not accused of row is auto industry one of the important source of CO2,so from the perspective of supply chain,the automobile industry monitor carbon emissions,is a feasible method to achieve carbon reducing overall goal.In order to achieve the goal of energy conservation and emission reduction,this paper studies the carbon emission of automobile supply chain based on the theory of low-carbon supply chain and the comprehensive application of game theory and backward induction and other relevant knowledge.First,calculate the CO2 generated by the automobile supply chain.According to the summary and analysis of the characteristics and definitions of the automobile supply chain,the emission coefficient method recommended by IPCC was used to calculate the energy consumption data of each link of the automobile supply chain and quantify the CO2 emissions in each link of the supply chain.Then,on the basis of carbon emission measurement of automobile supply chain,three game models of emission reduction strategy of automobile supply chain are established: pure carbon trading right game model,pure emission reduction investment game model and mixed emission reduction investment game model.Finally,the equilibrium results are analyzed respectively from the aspects of emission reduction investment cost,carbon trading price,emission reduction cost sharing proportion and mixed proportion.It is found that the hybrid investment strategy adopted by the automobile supply chain has higher emission reduction rate,and within a certain range of investment cost coefficient,manufacturers and retailers have greater profits.The level of carbon trading price will directly affect the decision-making of emission reduction strategy of automobile supply chain,and the emission reduction rate of automobile supply chain will increase with the increase of the cost sharing rate of emission reduction.The retailer's profit increases gradually with the increase of the mixture ratio,while the manufacturer's profit increases first and then decreases.In automobile supply chain carbon emissions measurement and mitigation strategy research,not only is advantageous to the automotive supply chain check the situation of CO2 produced themselves,to lay the foundation for complete supply chain enterprise,but also can provide reference for government departments to make carbon reduction policy,at the same time to the study of CO2 emissions in other industries also has a certain significance. |
